NieAFinished up season two of Mass Production Girl Riko, and it's such a good series. I like the approach it took, not simply being a continuation of the first season. It still had some fun easter eggs referring back to season one.
I've been impressed with how philosophical the show is, using plastic model building as a metaphor for tackling day to day life. Of course, it's also a great way for Bandai to promote plastic model kits, too. 
I also learned that Bandai Spirits has an idol group called Linkl Planet, which provides some of the support characters in the series, and I need to investigate this further as well.
Now I'm ready to see what season three has in store!
